During the War of 1812, British and Indian forces under Sir Isaac Brock defeat Americans under General Stephen Van Rensselaer at the Battle of Queenstown Heights, on the Niagara frontier in Ontario, Canada. The British victory, in which more than 1,000 U.S. troops were killed, wounded, or captured, effectively ended any further U.S. invasion of Canada. Sir Isaac Brock, Britain’s most talented general in the war, was killed during the battle.
